EtherCAT supports multiple network architectures and topology variations. For example, EtherCAT can be used by a master device to exchange information with distributed Input / Output (I/O) modules within a redundant EtherCAT ring. A basic EtherCAT network is mainly composed by a master and one or more slaves that exchange information cyclically between them; thus, master sends outputs and receives inputs from slaves. These outputs and inputs variables are allocated in datagrams, and these datagrams shape the frames that will travel around the EtherCAT network.

EtherCAT bus (ethernet for control automation technology) is a high performance communication bus based on Ethernet. The main objective of Ether-CAT is the ability to use certain layers of Ethernet in automation and control applications requiring small data update times (also called cycle times), with low jitter values (for synchronization purposes) and low cost hardware. It is suitable to be used on machine-tools application domain.
EtherCAT
Published in Sunit Kumar Sen, Fieldbus and Networking in Process Automation, 2014
EtherCAT (Ethernet Control Automation Technology), developed by Beckhoff Automation GmbH, Germany in 2003, is an open protocol based on Ethernet physical layer and is now managed by EtherCAT Technology Group (ETG). It is standardized in IEC 61158 and uses standard Ethernet frame IEEE 802.3. EtherCAT uses a summation frame, processing on the fly, and an open software/modified Ethernet approach for faster data transfer.
Ethernet-Based Servo-Hydraulic Real-Time Controller and DAQ at ELSA for Large Scale Experiments

ELSA Real-time EtherCAT® Controller and DAQ system (ELSAREC) is the final outcome of this new approach, and the development work started in 2012. ELSAREC is based on EtherCAT® data transfer protocol and technologies that are more and more adopted in the industrial automation sector. EtherCAT® is a transfer protocol based on an Ethernet bus that allows the creation of device networks with different topologies (i.e. lines, trees, or stars). The devices connected are generally Input-Output modules, conditioning apparatus, or CPUs that exchange information by means of the EtherCAT® bus with a clock sampling of the order of the millisecond or even smaller. This technology is particularly attractive for control automation and DAQ in many applications because it makes it possible to accurately synchronize devices spatially distributed with a simultaneousness of the order of tens of microseconds (EtherCAT® Technology Group 2020) that is more than enough in medium to large size mechanical systems.
Collision-free path planning based on new navigation function for an industrial robotic manipulator in human-robot coexistence environments
Published in Journal of the Chinese Institute of Engineers, 2020
Chun-Chieh Chan, Ching-Chih Tsai
In many real applications, real-time computations are essential for environments in which humans and robots cooperate or coexist. EtherCAT (Ethernet Control Automation Technology) is a real-time industrial Ethernet technology that uses Ethernet to reduce costs and cycle time and which has a 100 Mbit/s transmission rate and allows precise synchronization. Moreover, EtherCAT can also cover hundreds of devices within a network without modifications to the hardware, so it is widely used for industrial automation systems and real-time control systems (Abdullah et al. 2016; Tsai et al. 2019).
